JAVA Language

Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. TCCI at Bopal-Satellite-Ahmedabad.

The Java language’s programming paradigm is based on the concept of OOP, which the language’s features support. Here, code blocks are modularized into methods and delimited by braces ({and}), and variables are declared before they are used.

Java language includes Object Oriented Programming, Java Compiler, Java virtual machine, just in time Compiler, Java Runtime Environment, Garbage Collector, Packages, interface etc…

We teach following topics in java:

  1. Basic Introduction to Java
  2. Object Oriented Programming
  3. Basic Data types and Variables
  4. Modifier Types
  5. Operators
  6. Loop controls
  7. Decision Making
  8. Arrays and String
  9. Methods
  10. Inheritance
  11. Interface

Recursion in Programming – tccicomputercoaching.com

Recursion is a method of solving a problem where the solution depends on solutions to smaller instances of the same problem. Such problems can generally be solved by iteration, but this needs to identify and index the smaller instances at programming time.

Most computer programming languages support recursion by allowing a function to call itself from within its own code.

To solve a problem recursively means that you have to first redefine the problem in terms of a smaller sub problem of the same type as the original problem.

Recursion-tcci

Example,

If we want to sum of 1 to 10 no without loop then we can use recursion like following:

int sum(int n)

{

If (n == 1)

{

return 1;

}

else

{

return n + sum(n-1);

}

void main()

{

int no;

//input value of no at runtime….

ans = sum(no);

//display ans here…

}

}

What is use of Recursion?

Recursion is made for solving problems that can be broken down into smaller, repetitive problems. It is especially good for working on things that have many possible branches and are too complex for an iterative approach. One good example of this would be searching through a file system.

In the above summation problem, to sum-up n integers we have to know how to sum-up n-1 integers. Next, you have to figure out how the solution to smaller sub problems will give you a solution to the problem as a whole. This step is often called as a recursive leap of faith. Before using a recursive call, you must be convinced that the recursive call will do what it is supposed to do. You do not need to think how recursive calls works, just assume that it returns the correct result.

What is Function Prototype- tccicomputercoaching.com

A function prototype is function declaration which present function’s name, parameters and return type. It doesn’t contain function body.This is written always outside the main function.

Function-Prototype-simple

A function prototype gives information to the compiler that the function may later be used in the program.

Syntax:

Returntype

fun name(datatype var1, datatype var2….);

What is method overriding in Java? – tccicomputercoaching.com

When method of child class redefines the method of parent class then it is called method overriding in Java.

method-overriding-in-Java_simple

Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. In this case the method in parent class is called overridden method and the method in child class is called overriding method.

A method can only be written in Subclass not in same class. The argument list should be exactly the same as that of the overridden method. The return type should be the same or a sub type of the return type declared in the original overridden method in the super class. A method declared final cannot be overridden.

Example:

1. class Human

2. { public void eat()

3. { System.out.println(“Human is eating”); }}

4. class Boy extends Human

5. { public void eat()

6. { System.out.println(“Boy is eating”); }

7. public static void main( String args[])

8. { Boy obj = new Boy(); obj.eat(); }}

What is Abstract class and abstract Method in Java -tccicomputercoaching.com


Abstract
means something, which is in thoughts but not it exists in reality. It is like that we know that what should be done, but we don’t know how it would be done.

Take an example, there is a ‘Shape’ class which contains a method ‘area()’ but we cannot implement area() method here as we do not know what will be the shape(a square, a rectangle, a triangle or any other shape) in future. In that case, we will declare area() in the Shape class and will implement the same method in our subclasses as per the requirement.

Abstract class & Method in Java_simple

Example:

1. public abstract class Shape

2. {

3.       public abstract void area(int var); // Abstract method

4. }

6. public class Circle extends Shape

7. {

8.      int radius;

9.      double pi=3.14;

10.    public void area(int var)

11.      {

12.         radius=var;

13.         System.out.println(“Arear of Circle: “+(pi*radius*radius));

14.       }

15.   }

16. public class Square extends Shape

17.  {

18.    int side;

19.    public void area(int var)

20.      {

21.         side=var;

22.         System.out.println(“Area of Square: “+side*side);

23.      }

24. }

25. public class Result

26. {

27.       public static void main(String[] args)

28.         {

29.             Shape obj=new Square();

30.             obj.area(4);

32.             Shape obj1=new Circle();

33.             obj1.area(3);

34.          }

35. }

In JAVA, Abstraction can be achieved using the abstract class, abstract methods, and interface. Using the abstract class we can achieve the different level of abstraction, but using the interfaces we can achieve 100% abstraction.

Abstract Class:

1. An abstract class would be declared using ‘abstract’ keyword.

2. Creation of object is not possible of an abstract class.

3. It may contain data members, methods, abstract methods, constructors.

4. Data members can’t be abstract.

5. It must be inherited by the subclass(es) using ‘extends’ keyword.

6. The subclass should implement each and every abstract method declared in Super Class. Otherwise, subclass would act like abstract class which needs to be extended further.

Abstract Method:

1. An abstract method can be placed within an abstract Class only.

2. It would be declared using ‘abstract’

3. The abstract method should be declared only without any implementation

4. It can be implemented only in the subclass(concrete class) using ‘extends’ or ‘implements’.

What is Inner class in Java? – tccicomputercoaching.com

Inner class means one class inside another class or we can say that one class is member of another class.

java-inner-class

Such class is known as nested class.

Syntax:

class OuterClass {

// …

class NestedClass {

// …

}

}

How to access inner class?

To access the inner class, create an object of the outer class, and then create an object of the inner class.

There are basically four types of inner classes in java.

1) Nested Inner class
2) Method Local inner classes
3) Anonymous inner classes
4) Static nested classes

The nested class makes code more readable and maintainable because there are group’s of related classes.

Why there is no switch statement in python? – tccicomputercoaching.com

Switch case is a powerful decision-making construct commonly used in modular programming.

Unlike other programming languages, Python doesn’t provide a switch case instrument over the self.

Switch-statement-in-python_Simple

However, it has many other constructs like a dictionary, lambda function, and classes to write a custom implementation of the Python switch case statement.

One example of Switch in Python :

Here, we define a function week() to tell us which day a certain day of the week is. A switcher is a dictionary that performs this mapping.

1

As you can see, for values other than the ones we mention in the switcher, it prints out “Invalid day of week”. This is because we tell it to do so using the get() method of a dictionary.

TCCI teach so many Programming Languages to Diploma-Degree Engineering students, School students ,BCA ,MCA , PGDCA, BSC_IT , and any Non-IT person.
